react-i18n-auto专门为中文国际化提供的自动化方案,快速迭代国际化开发,方法如下安装
安装安装
npm install react-i18n-auto --save-dev

npm install react-i18n-auto --save-dev
第一步:添加babel插件配置(.babelrc添加方式)
第一步:
{
"plugins": [

"@babel/plugin-transform-runtime",

"react-i18n-auto",

"..."
]
}
{
"plugins": [

"@babel/plugin-transform-runtime",

"react-i18n-auto",

"..."
]
}第二步:添加自动化配置 i18n.config.js
第二步:
const generator = require('react-i18n-auto/generator')
const path = require('path')

generator.gen({

excluded: /node_modules|output/, //排除文件选项(默认为:/node_modules/)

src: path.resolve(__dirname, './code'), //源文件目录(必选)

outputPath: path.resolve(__dirname, './output'), //国际化配置输出目录(必选)

})


const generator = require('react-i18n-auto/generator')
const path = require('path')

generator.gen({

excluded: /node_modules|output/, //排除文件选项(默认为:/node_modules/)

src: path.resolve(__dirname, './code'), //源文件目录(必选)

outputPath: path.resolve(__dirname, './output'), //国际化配置输出目录(必选)

})

然后运行 node i18n.config.js 自动生成配置文件,将localePolyfill.js,localeUtils.js,语言包文件自动生成到outputPath目录下localePolyfill.js暴露全局方法 $AI, $$AI 和全局变量 LOCALE (语言包),LOCALE_VERSION (语言包版本)配置请移步至react-i18n-auto github主页react-i18n-auto github主页第三步:修改webpack配置,为每一个entry入口添加localePolyfill.js
第三步:
// webpack.config.js
const path = require('path')
module.exports = {
entry: {
main: [

path.resolve(__dirname, './output/localePolyfill.js'),

path.resolve(__dirname, './src/index.js')
],
...
},

// webpack.config.js
const path = require('path')
module.exports = {
entry: {
main: [

path.resolve(__dirname, './output/localePolyfill.js'),

path.resolve(__dirname, './src/index.js')
],
...
},
第四步:修改当前语言(中文无需加载语言包)
第四步:
import React from 'react'
import en_US from '../output/en_US/locale'
import localeUtils from '../output/localeUtils'

localeUtils.locale(en_US)
// lolale.js
module.exports = {
'I_2gaaanh': 'Student',
'I_2aq02r1': 'Teacher'
}


import React from 'react'
import en_US from '../output/en_US/locale'
import localeUtils from '../output/localeUtils'

localeUtils.locale(en_US)
// lolale.js
module.exports = {
'I_2gaaanh': 'Student',
'I_2aq02r1': 'Teacher'
}

第五步:唯一的额外的工作,动态加载语言包时(如果语言包已提前加载则无需此操作)
第五步:修改前
// const.js
export default Const = {
SelectOptions:[
{

name:'学生',

value:'student',
},
{

name:'教师',

value:'teacher',
},
]
}

// const.js
export default Const = {
SelectOptions:[
{

name:'学生',

value:'student',
},
{

name:'教师',

value:'teacher',
},
]
}

// app.js
import React from 'react'
import Const from './const'

export default class App extends React.Component {
render () {
return
}
}


// app.js
import React from 'react'
import Const from './const'

export default class App extends React.Component {
render () {
return
}
}

由于const为常量,当语言包LOCALE更新时,const并不会得到更新,需要手动调用$AI,类似的情况都需要手动更新修改后
import React from 'react'
import Const from './const'

export default class App extends React.Component {
render () {
return
}
}


import React from 'react'
import Const from './const'

export default class App extends React.Component {
render () {
return
}
}


// 编译后的const.js
// 所有的中文对应的字段,自动添加$_前缀,值为对应中文的uuidKey

export default Const = {
selectOptions: [{
name: '学生',
$_name: "I_2gaaanh",
value: 'student'
}, {
name: '教师',
$_name: "I_2aq02r1",
value: 'teacher'
}]
};


// 编译后的const.js
// 所有的中文对应的字段,自动添加$_前缀,值为对应中文的uuidKey

export default Const = {
selectOptions: [{
name: '学生',
$_name: "I_2gaaanh",
value: 'student'
}, {
name: '教师',
$_name: "I_2aq02r1",
value: 'teacher'
}]
};

ps :通过代理getter,或提前加载语言包则可跳过步骤5,具体方法可自行尝试
